To all 'whom it may concern:

Be it lnown that l, HARRY GEHMAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Non-Bellable Bottle, of which the following is a specii'ication.

The invention relates to improvements in non-reiillable bottles.

The object of the present invention is to improve the construction of non-reiiilable bottles, and to provide a simple non-refillable bottle, adapted to be blown with the same facility as an ordinary bottle, whereby it is adapted to be easily and cheaply manufactured.

A further object of the invention is to provide a non-reiillable bottle of this character having a valve mechanism, capable of effectually preventing a bottle from being fraudulently relilled, or its contents adulterated, and adapted, should it be subjected to en terior pressure, to close the necli of the bottle and prevent a liquid from being either' poured from the bottle or into the same.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto a pended; it 'oeing understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

ln the drawingz-lligure l is a vertical sectional view of a non-refillable bottle, constructed in accordance with this invention, the valve mechanism and the guard being shown in elevation. ig. 2 is a similar view, the valve mechanism and the guard being shown in section. 3 is a horizontal sectional view on the line 3 8 of l. fl is a detail perspective view of the guard. llig. 5 is a detail sectional view, illustrating the manner in which the valve is interlccled with the valvecasing when the bottle is subjected to external pressure. Fig. 6 is a detail perspective view of the casing. llig. 7 is a detail view of the elastic Y sleeve.

Lilie numerals of reference designate corresponding parts in all the iigures of the drawing.

l designates a bottle provided with a cylindrical neck 2, having a reduced lower portion 8, forming a seat or stop for a valve casing 4, constructed of glass, or other suitable material. The neck of the bottle is provided with a smooth interior, and is adapted to be blown with the same facility as an ordinary bottle, and the device is applicable to bottles of various sizes, and may be applied to all kinds of receptacles having a neck. The up er portion of the valve casing is cylindricapl, and its lower portion 5 is tapered to form a valve seat 6, the tapered portion being slightly rounded and conforming to the configuration of and spaced from the reduced portion 3 of the neck of the bottle. An elastic sleeve or packing ring 7 of corl, rubber, or other suitable material is arranged on the exterior of the valve casing, and is intern posed between the lower portion or the same and the neclr of the bottle, as clearly illus trated in Figs. l and 2 of the drawing, to form an air tight connection. yllhe upper portion of the valve casing is provided with an exterior annular boss or flange 8, forming a shoulder and receiving the upper edge of the elastic sleeve or ring 7. rlfhe elastic sleeve or ring 7 is placed on the valve casing before the latter is introduced into the bottle, and when the liquid contents of the bottle come in contact with the corlr sleeve or ring, the latter swells and forms a liquid and air tight connection, and at the same time prevents any lack of uniformity in the necks of the bottles from affecting the perfect fitting of the valve casing within the same.

The valve casing receives a soft elastic ball valve 9 of less specific gravity than water, preferably constructed of highly elastic rubber, and adapted to be readily opened by the liquid contents of the bottle, when the latter is inverted, and capable also of forming a liquid tight closure when arranged on the seat of the valve casing. rlhe highly elastic ball valve is adapted to follow the flow of the liquid, should an attempt be made to refill the bottle, and any liquid entering the neclr of the bottle will carry the valve to its seat, and if pressure be resorted to for forcing the liquid into the bottle, the valve will be forced partially through the inner end ofthe valve casing, as illustrated in Fig. 5 of the drawing, and the protruding portion will expand beyond the inner end of the valve casing, and will operate to lock the valve on the VII same after ythe external pressure has been removed. This will close the neck of the'bottle and prevent the passage of a liquid in either direction, so that nothing can be poured into or out of the bottle.- Shouldan attempt be made to refill the bottle before its original contents have been consumed, the valve, if locked in the manner above described, will operate to render the bottle useless and prevent any liquid remaining in the same from being ydecanted therefrom. rlhe lower tapered portion' of the valve casing is provided below the seat with an interior wall 5, adapted to engage the `ball valve, when the latter is forced inward and forming a lower comparatively sharp edge, beyond which the protruding portion of the ball valve expands and engages the lower fiat edge 5b of thel valve casing. rl`his construction enables the ball valve to be firmly retained in its position, when it is forced pare tiallythrough the lower or inner end of the valve seat.

Thef valve is positively held on its seat when the bottle is in any position between a horizontal and a vertical position, by means of a weight 10, which is in the form of a ball ofthe same diameter as the interior of the cylindrical portion of the valve casing. The ballfshaped weight, whichmay be constructed of any suitable material, isr relatively'heavy while the ball valve is relatively light, and owing to its snug lit within the upper portion of the valve casing, it will be impossible through any lateral shaking of the bottle to cause any liquid to percolate through the valve casing and enter the body portion of the bottle. Also as the valve is relatively light, any attempt to introduce a liquid into the vbottle by shaking it vertically will be equally ineffectual to displace the valve from its seat.

The outward movement of the weight and the valve is limited by a guard 11, constructed of glass, porcelain, or any other suitable material, and consisting of a substantiallyy cylindrical body portion, open at the top and closed at the ybottom and provided with depending supporting legs 12, which rest upon the upper edge of the valve casing.' VThe depending supporting legs are provided with upwardly and inwardly inclined inner edges 13, whichconverge towards the bottom ofthe bod portion of the guard and which, when the ottle is in a horizontal position, present an inclined supporting face to the all-shaped weight for causing the same to roll inwardly to maintain the valve on its seat, when the bottle is in such position.

This will prevent any liquid from entering the lbottle should it be partially submerged vin a horizontal position in a vessel containing the liquid. VThe body portion ofthe guard provided with horizontally disposedopen- Aings 14,' and it is recessed below the opening at 15, nthe openings 14 Aoccurring between the spaces above the supporting legs, and the uncut intervening portions between the recesses forming continuations of the said legs. The openings 14 communicate with the interior of the guard, and tortuous passages are lthus formed, which permit a free discharge of the contents of the bottle, and at the same time prevent a wire, or other instrument, introduced into the neck of the bottle, from reaching and interfering with the operation of the valve and the weight. The bottom 16 of the guard has a concave upper face, as clearly illustrated in Fig. 2.of the drawing. This will tend to bend the ,end of a wire upward should it come in contact with the bottom. The openings 14 are located above the concave bottom, and the guard is rovided above the openings with beveled e ges 17, extending upwardly and outwardly from the interior of the guard. This construction serves to direct an instrument away from the valve mechanism, should an attempt b made to tamper with the same.

The openin s 14 space the bottom 16 from the cylindrica body portion of the guard v11, and the legs 12 are connected with and support both the cylindrical body ortion and the bottom 16, which is locate above the open upper end of the valve casin g to limitthe upward movement of the ball and `the ball valve.

The guard is provided at its upper end with an exterior annular recess 18, and it is reed, when the bottle Ais inverted. The openings 14 form a vent to permit air to enter the bottle as the liquid is poured therefrom, so that a'free discharge of the contents of the bottle is assured.

' Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:-
